摘要

The wiper arm has a bearing or fixing-piece (1) for fixing the wiper arm (3) at a windshield wiper drive, a wiper arm element (2), connected with the bearing- or fixing-piece by a wiper arm joint (7), for a wiper blade. A spring element by bridging the wiper arm joint produces a wiper blade contact force with which the wiper blade fits against a vehicle disk (8) during a wiping operation. The wiper arm element is flexibly formed, and the spring element is a buckling spring (11). The wiper arm element is made of plastic, particularly a fiber-reinforced.
